Not satisfied with 19 years in charge of the gas-rich central Asian state, Nazarbayev urged scientists today to unlock the secret to immortality.

The 70-year-old leader stressed in a speech that a new scientific research institute in the capital Astana should study “rejuvenation of the organism,” as well as “the human genome, production of human tissue and creation of gene-based medicines”.

In an aside to students, Nazarbayev added: “As for the medicine of the future, people of my age are really hoping all of this will happen as soon as possible.”

Two months ago an ethnic Korean delegate at Kazakhstan’s people’s assembly proposed that Nazarbayev should stay in power until 2020. The president answered: “Maybe, then, you’ll offer me an elixir of youth and energy – maybe you have such potions in Korea … I’m willing to go on until 2020, just find me an elixir.”

Today was the third time in just over a year that Nazarbayev has urged scientists to find a way to stave off death.
